Research and Application of Constant Motion Controlled by Two-axle

Some devices require non-circular parts high surface quality. However, when hardening surfaces of these parts, it is important to choose specific motion control card to keep induction heating spots constant moving. Following mathematical model of constant motion, we program in the computer to control two-type movement of general induction hardening bed in order to achieve linked control of workpiece swing and induction spots linear motion. By test detection we can get relative velocity of induction heating spots unchanged basically and meet the requirements of parts' induction hardening. This research has very important significance of solving problems of non-circular parts' surface hardening.
